At first sight the little insect exhibiting these characters might 

 be mistaken for a species of Notiophilus of Dumeril, or at least 

 be regarded as belonging to a cognate genus. Its large and very- 

 prominent eyes, the shape in some measure of its thorax, the 

 striae of the disk of its elytra less impressed with puncta than 

 those of the limb, as likewise its frontal furrows, give it no in- 

 considerable appearance of affinity to it. But a closer inspec- 

 tion proves that this is merely an appearance, and that in fact 

 it belongs to a different tribe connected with the Harpalida. 

 Notiophilus and its genuine affinities are distinguished by a par- 

 ticular character indicating some difference in their mode of 

 taking or retaining their prey. The great majority of the Ca- 

 rabi of Linne are remarkable for a notch on the inner side of 

 their anterior tibiae, armed at its upper angle by a spur, which 

 appears to be of use to them for the above purpose. In the 

 Harpalida and many others this notch is nearly in the middle of 

 the tibia ; but in Notiophilus and its affinities its situation is close 

 to its apext. Catascopus, with respect to this part, falls into the 

 former tribe J. Again, in Notiophilus the labium consists only of 

 a single lobe, or at least the lateral ones are much shorter than 

 the central § ; but in the Harpalidce they are as long or longer |[. 

 In Catascopus also they are very conspicuous, being twice the 

 length of the central lobe ^. In ElaphrtiSy Notiophilus, Blethi-
